    Product Description

    α,β-Methyleneadenosine 5'-triphosphate (αβ-methylene ATP) is a phosphonic analog of ATP that is characterized by the replacement of the bridging oxygen atom between the α- and β-phosphate groups with methylene. It is an agonist of P2X purinoceptors P2X1 and P2X3 (EC50 = ~1 µM) and is ~1,000-fold less potent at P2X2, P2X receptors 4-7, and P2Y receptors.1,2,3,4 Persistent activation of purinoceptors results in desensitization, resulting in an antagonist-like effect of αβ-methylene ATP.5 αβ-methylene ATP is used as a stable analog of ATP (Item No. 14498) to study the interaction of ATP with kinases and other proteins.6,7 It weakly binds and inhibits adenylate cyclase in a calcium-dependent manner (Ki= ~0.5 mM).8,9
